Description

Technical Field

[0001] The invention relates to the technical field of guide rail lifting equipment, in particular to a guide rail AGV automatic traction device for transporting ground wave-absorbing materials. Background Art

[0002] When testing a vehicle in an anechoic chamber, in order to allow the tested vehicle to drive onto the turntable in the middle, the wedges placed in the area between the anechoic chamber door and the turntable need to be moved out (several wedges are fixed on a base plate to facilitate centralized transportation. The wedges are conical carbon sponge absorbing materials, made of polyurethane foam plastic infiltrated in a carbon glue solution). After the ground absorbing material is removed, the vehicle can drive onto the testing table located in the center of the anechoic chamber.

[0003] The traditional method is to manually operate a forklift to move the wedge away and allow the vehicle to pass. After the vehicle reaches the turntable, the wedge is moved back to its original position. After the test is completed, this operation is repeated. When moving, it is necessary to avoid collisions between adjacent wedges. This operation method is time-consuming, labor-intensive, and inefficient, and cannot meet the requirements for rapid vehicle passage. In one solution, a lifting device is set up on the top of the anechoic chamber. When testing an incoming vehicle, the wedge on the ground is lifted, which is convenient and quick. However, due to its special structure, the anechoic chamber needs to be covered with wedges, so the lifting mechanism needs to be hidden. The lifting mechanism is above the wedge, and a gap is reserved at the wedge for the hook to pass through, which destroys the integrity of the absorbing material coverage. The existence of the gap still has a certain impact on the experimental results. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-9 The embodiment of the present invention provides a guide rail type AGV automatic traction device for transporting ground absorbing materials, comprising a guide rail 1 fixedly installed on the top of a factory building, wherein the guide rail 1 is fixedly connected to a base plate 3 through a connecting frame 2, and further comprising:

[0033] The hoisting mechanism is arranged on the guide rail 1, and includes a first rotating shaft 5, a drum 51, a connecting rope 82, and a hook 81. The drum 51 is fixedly mounted on the first rotating shaft 5, and the hook 81 is connected to the drum 51 through the connecting rope 82;

[0034] A power unit 4, the power unit 4 is used to drive the hook 81 to move in the vertical direction, and the power unit 4 and the first rotating shaft 5 are connected to each other through a first transmission part 41;

[0035] The avoidance plate 71 is disposed on the substrate 3. The avoidance plate 71 has a first state and a second state. In the first state, the avoidance plate 71 is embedded in the substrate 3. In the second state, the avoidance plate 71 is separated from the substrate 3 so that the hook 81 can pass through the substrate 3 smoothly.

[0036] The flip unit 7 is connected with the first rotating shaft 5 by transmission. The flip unit 7 is used to drive the avoidance plate 71 to switch to the second state. The flip unit 7 includes a moving structure, a rotating structure and a self-locking structure. When the hook 81 moves downward, the moving structure drives the avoidance plate 71 to move upward to separate from the substrate 3. The rotating structure then drives the avoidance plate 71 to rotate 90 degrees, and then the self-locking structure locks the avoidance plate 71.

[0037] In the embodiment of the present invention, the guide rail 1 needs to be installed on the top of the radio wave darkroom, and the base plate 3 is fixedly installed on the guide rail 1 through the connecting frame 2, the sharp wedge 31 is installed on the base plate 3, and the power unit 4 is installed on the guide rail 1. The first rotating shaft 5 can be driven to rotate by the power unit 4. When the first rotating shaft 5 rotates, the connecting rope 82 can be released or reeled up, so that the hook 81 can be pulled by the connecting rope 82 to move in the vertical direction to complete the hoisting of the sharp wedge 31 on the ground. When the hook 81 moves downward, the single hook 81 is flipped. After element 7 receives the transmission of first rotating shaft 5, moving mechanism will first lift up avoiding plate 71, so that avoiding plate 71 will be separated from base plate 3, after avoiding plate 71 moves up a certain distance, rotating structure will drive avoiding plate 71 to rotate, until avoiding plate 71 moves up to the highest point, at this time, avoiding plate 71 has been separated from base plate 3 and switched from horizontal state to vertical state, so the base plate 3 will have notch or exposure, and at this angle, self-locking structure will lock the position of avoiding plate 71, ensure that when hook 8 During the descent of the vehicle 1, the notch is always in an open state to avoid the phenomenon of the avoidance plate 71 being reset during the descent. The hook 81 is continuously lowered until it lands on the absorbing material close to the ground. The hook 81 is connected to the absorbing material on the ground. The power unit 4 is turned over and the hook 81 moves up to lift the absorbing material on the ground. The upward moving distance varies arbitrarily according to different vehicle models and needs to be at least 50 cm higher than the vehicle model to be tested. After the vehicle enters the central test bench, the hook 81 is lowered and the absorbing material is placed again on the On the ground, the hook 81 is detached from the absorbing material. At this time, the hook 81 is continuously raised. After the hook 81 moves to the upper part of the substrate 3, the self-locking mechanism is unlocked, and the moving structure drives the avoidance plate 71 to be reinstalled. The avoidance plate 71 is driven downward by the rotating structure so that the avoidance plate 71 is re-embedded in the substrate 3. In this way, the wedge 31 on the avoidance plate 71 and the wedge 31 on the substrate 3 can be neatly arranged again, ensuring that the entire anechoic chamber is completely covered by the wedge 31, which helps to improve the detection effect of the anechoic chamber.

[0038] In an embodiment of the present invention, the movable structure includes a second rotating shaft 6, a second transmission part 52, a driving disk 61, a lifting block 72, an L-shaped lifting rod 73, and a swing arm 74. The avoidance plate 71 is rotatably connected to the lifting block 72, the lifting block 72 is slidably connected to the connecting frame 2, the L-shaped lifting rod 73 is slidably connected to the connecting frame 2, the lower end of the L-shaped lifting rod 73 is attached to the lower part of the lifting block 72, the lower part of the swing arm 74 is hinged to the upper part of the L-shaped lifting rod 73, the upper part of the swing arm 74 is hinged to the driving disk 61, the driving disk 61 is fixedly installed on the second rotating shaft 6, and the second rotating shaft 6 and the first rotating shaft 5 are connected by the second transmission part 52.

[0039] When the driving plate 61 is rotated, the swing arm 74 is driven upward, and the swing arm 74 moves upward to pull the L-shaped lifting rod 73 upward. The lower part of the L-shaped lifting rod 73 is attached to the lower part of the lifting block 72. When the L-shaped lifting rod 73 moves upward, an upward thrust is applied to the lifting block 72 to make the lifting block 72 move upward. The avoidance plate 71 is rotatably connected to the lifting block 72. When the lifting block 72 moves upward, the avoidance plate 71 is synchronously driven to move upward, so that the avoidance plate 71 is separated from the substrate 3. By moving the avoidance plate 71 upward, sufficient turning space is obtained to avoid interference between the avoidance plate 71 and the substrate 3.

[0040] In an embodiment of the present invention, the rotating structure includes a gear 75 and a rack 76. The gear 75 is fixedly mounted on the avoidance plate 71, and the rack 76 is fixedly mounted on the connecting frame 2. The rack 76 is located on the moving path of the gear 75 in the vertical direction.

[0041] As the hook 81 continues to move downward, the lifting block 72 will continue to move upward. The gear 75 is fixed on the avoidance plate 71, and the rack 76 is set on the moving stroke of the avoidance plate 71. After the avoidance plate 71 moves up a certain distance, the gear 75 will mesh with the rack 76. As the lifting block 72 continues to move upward, the gear 75 will inevitably rotate at a moving angle. When the gear 75 rotates, the avoidance plate 71 will inevitably rotate from a horizontal state to a vertical state. In this way, the notch on the base plate 3 will be exposed to ensure the smooth passage of the hook 81.

[0042] In the embodiments of the present invention, please refer to Figure 6-9The self-locking mechanism includes a column 77, a pressure plate 771, a support block 78, and an elastic member 781. The column 77 is fixedly mounted on the base plate 3, the pressure plate 771 is slidably sleeved on the column 77, one end of the pressure plate 771 extends above the hook 81, the support block 78 is slidably inserted on the connecting frame 2, and the elastic member 781 applies a thrust toward the pressure plate 771 to the support block 78.

[0043] When the lifting block 72 moves to the highest point, the avoidance plate 71 is just in the second state, and at this time, the hook 81 drops to the base plate 3, and during the descending process of the hook 81, the pressure plate 771 will drop accordingly. When the pressure plate 771 drops to the support block 78, the pressure plate 771 applies a thrust to the support block 78. Under the action of the thrust, the support block 78 overcomes the elastic force of the elastic member 781 and moves toward the lifting block 72. The support block 78 will be smoothly inserted into the bottom surface of the lifting block 72, which will fix the height of the lifting block 72, and synchronously, the avoidance plate 71 will be in the second state. The positioning plate 71 will also be fixed, and at this time, the hook 81 will continue to move downward. During the downward movement, the driving disk 61 will continue to rotate, so that the driving disk 61 will move downward with the swing arm 74. During the downward movement of the swing arm 74, the L-shaped lifting rod 73 will move downward synchronously, and the L-shaped lifting rod 73 and the lifting block 72 will fit together. The lifting block 72 is restricted and fixed by the supporting block 78, and the L-shaped lifting rod 73 can continue to move up and down under the action of the driving disk 61 without affecting the position of the lifting block 72, so as to ensure that the hook 81 can continue to move down to the ground. The absorbing material on the ground is lifted by the hook 81 to facilitate the vehicle to enter the test platform in the center of the anechoic chamber. After the vehicle enters, the hook 81 moves down and puts down the absorbing material again. The hook 81 is driven to reset by the power unit 4. When the hook 81 moves to the top of the substrate 3, it will contact the pressure plate 771 and simultaneously drive the pressure plate 771 to move up. Therefore, the pressure plate 771 is separated from the support block 78. Under the rebound force of the elastic member 781, the support block 78 will be separated from the bottom of the lifting block 72. In this way, under the action of gravity, the lifting block 72 During the downward movement, due to the meshing of the gear 75 and the rack 76, the avoidance plate 71 will reset and rotate. When the avoidance plate 71 flips to the horizontal position, the avoidance plate 71 will continue to move downward until the avoidance plate 71 is completely embedded in the substrate 3. In this embodiment, the flip unit 7 uses the power provided by the downward movement of the hook 81 to passively open and close the avoidance plate 71. This ensures that during the vehicle measurement process, the hook 81 is perfectly hidden above the absorbing material, thereby increasing the coverage area of ​​the wedge 31 and helping to improve the detection effect of the radio wave darkroom.

[0044] In this embodiment, the entire device implements the concept of hidden installation. The equipment is suitable for being installed on the top of a factory building. Maintenance at these locations is very inconvenient. Therefore, the device minimizes the use of electromechanical equipment and adopts a single drive method globally. The power of the lifting and lowering of the hook 81 is used to passively realize the opening and closing of the avoidance plate 71, making maintenance more convenient.

[0045] In the embodiments of the present invention, please refer to Fig. 9 The end of the support block 78 closer to the pressure plate 771 is provided with an inclined surface, and the pressure plate 771 is adapted to the inclined surface. When the pressure plate 771 moves downward, it will squeeze the support block 78 to move toward the direction where the lifting block 72 is located.

[0046] Inclined surfaces are provided on both the support block 78 and the pressure plate 771. Thus, when the pressure plate 771 moves downward, the pressure of the pressure plate 771 is decomposed into a lateral force on the support block 78, prompting the support block 78 to resist the displacement of the elastic member 781, so that the support block 78 moves to the bottom of the lifting block 72 to limit the height of the lifting block 72.

[0047] For an embodiment of the present invention, please refer to Figure 6-7 The shape of the L-shaped lifting rod 73 is set to be “L” shape, and the horizontal surface of the L-shaped lifting rod 73 is attached to the lower part of the lifting block 72.

[0048] The horizontal section of the L-shaped lifting rod 73 is attached to the lower surface of the lifting block 72, and the vertical section of the L-shaped lifting rod 73 is slidably connected to the connecting frame 2. The L-shaped lifting rod 73 can only be positioned in the vertical direction. The L-shaped lifting rod 73 and the lifting block 72 are attached to each other, so that after the lifting block 72 is fixed, the L-shaped lifting rod 73 can still move in the vertical direction.

[0049] In an embodiment of the present invention, the power unit 4 is configured as a servo motor, the first transmission part 41 is configured as a sprocket structure, and the output shaft of the servo motor and the first rotating shaft 5 are connected via the sprocket structure to ensure synchronous transmission between the two.

[0050] Through sprocket drive, it can be ensured that when the servo motor rotates, the first rotating shaft 5 rotates synchronously, and the transmission can be synchronously high. In addition, chain drive is suitable for scenes with higher loads. In this way, the stability of the hook 81 when lifting the absorbing material is guaranteed. Chain drive is a technology well known to those skilled in the art and will not be described in detail here.

[0051] The embodiment of the present invention includes a wedge 31, which is respectively mounted on the avoidance plate 71 and the substrate 3. The wedge 31 is a wave absorbing material, and the anechoic chamber needs to lay a slow wedge 31. The principle of the anechoic chamber and the wedge 31 is well known to the technical personnel, and will not be repeated here.

[0052] In the embodiment of the present invention, the hook 81 includes a counterweight and a hook body, the hook body is installed at the lower part of the counterweight, and the upper part of the counterweight is connected to the connecting rope 82. The shape of the counterweight is not fixed, and it can be a column or a rectangular structure. The hook body generally has an anti-drop structure. The counterweight and the hook body are both existing technologies and will not be described in detail here.

[0053] The embodiment of the present invention comprises a fixed pulley 83 which is rotatably connected to the guide rail 1 , one end of the connecting rope 82 is wound around the drum 51 , and the other end is connected to the hook 81 after passing through the fixed pulley 83 .

[0054] By setting the fixed pulley 83, it is ensured that the hook 81 is just above the avoidance plate 71, so that the hook 81 can smoothly pass through the notch on the base plate 3 during the downward movement, so as to ensure that the hook 81 smoothly moves down to the ground.

[0055] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
